Hi. Can't compile sample from pio_example folder:

hi,

either use an earlier version of this library, or use a more recent version of framework-arduinoespressif32 (3.x.x or upper)

[maxt]

That is the point.
I managed to use 1.0.1 version of library. It can be used in platformio dev environment.
However, AFAIK there is no (3.x.x or upper) version available in platformio (platformio/platform-espressif32#1225).

Looks like there is no way to use 2.0.1 with platformio.

[tobozo]

have you tried with pioarduino? unlike the official espressif core from platformio, this one is maintained and up to date 😉

[maxt]

Tried the sample in pioarduino with actual versions of library and platform libraries.
Technically, ethernet connection works,
hovewer, WiFI.onEvent(WiFiEvent);
doesn't appear to be working.
It doesn't catch any events in 'case' statement.
Even if I put debug print in "default:" section -it doesn't appear.

Changed while in setup() to:

  while( !eth_connected) {
    Serial.print(".");
    Serial.println(ETH.localIP());
    Serial.println(ETH.gatewayIP());
    Serial.println(ETH.dnsIP());
    IPAddress local = ETH.localIP();
    if (!local.toString().equals("0.0.0.0")){
      eth_connected = true;
    }
    delay( 1000 );
  }

and noticed, that it's finally get parameters over DHCP and since that any network related code works.

[tobozo]

good news, and thanks for sharing the solution 👍

can you share the platformio.ini too?

possible explanation for the WiFi Events not being fired: Ethernet doesn't use WiFi Events anymore with espressif core 3.x.x, they switched to Network Events instead.

My current platformio.ini

[env:esp32dev]
platform = https://github.com/pioarduino/platform-espressif32/releases/download/stable/platform-espressif32.zip
platform_packages = framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32/releases/download/3.1.1/esp32-3.1.1.zip
board = esp32dev

Can't provide PR right now, but since I got it working, so ready to post my solution:

#include <esp_event.h>

static void all_event_handler(void* handler_args, esp_event_base_t base, int32_t id, void* event_data)
{
    Serial.println("Caught an event!");
    Serial.println(base);
    Serial.println(id);
    
    if (ETHERNET_EVENT_CONNECTED==id){
      Serial.print("ethernet connected");
    }
    if (ETHERNET_EVENT_START==id){
      Serial.print("ethernet start");
    }

    if (IP_EVENT_ETH_GOT_IP==id && base == IP_EVENT){
      eth_connected = true;
    }
}

void setup()
{
  ESP_ERROR_CHECK(esp_event_loop_create_default());
  ESP_ERROR_CHECK(esp_event_handler_register(ESP_EVENT_ANY_BASE,ESP_EVENT_ANY_ID, all_event_handler, NULL));
  ...... 

}
